Question by Giancoli, Douglas C., Physics: Principles with Applications, 7th Ed., ©2014, Reprinted by permission of Pearson Education Inc., New York.
Problem 30
Q

Calculate the magnitude and direction of the currents in each resistor of Fig. 19–58.

Problem 30.
Figure 19-58.
A
R120=28.6 mA down, R74=28.6 mA right, R_{120} = 28.6 \textrm{ mA down, } R_{74} = 28.6 \textrm{ mA right, } R56=4.5 mA up, R110=24.1 mA up, R_{56} = 4.5 \textrm{ mA up, } R_{110} = 24.1 \textrm{ mA up, } R25=24.1 mA left.R_{25} = 24.1 \textrm{ mA left.}

The current I,1 is going to the left through the 5.8 V battery. The speaker accidentally says it's going to the right.

When I add -3.4643 and -1.4370 i keep getting -4.9013 not -5.9013 in regards to your solutions. Following the procedure outlined in the video, I actually get the wrong answer for the associated homework.
